Strengthen and reinforce damaged floor joists
Over time, floor joists can become weakened by moisture, wood rot, insect damage, or normal aging. When this happens, floors may begin to sag, feel bouncy, or show signs of structural stress. Floor joist sistering is an effective repair method that reinforces existing joists and restores strength to your floor system.
Side-by-side reinforcement that avoids full replacement
At Level Up Foundation Repair, we use proven joist repair techniques to help stabilize and strengthen your home's structure without the need for complete floor system replacement.
Joist sistering attaches new framing alongside an existing damaged joist, restoring strength to the floor above without the cost and disruption of replacing the entire system.
